Glyceryl trinitrate is a weak inhibitor of platelet aggregation in vitro. Its effect on platelet aggregation in response to U46619 (a thromboxane/endoperoxide receptor agonist) was studied turbidometrically in platelet-rich plasma from healthy volunteers. The object was to determine whether inhibition was influenced by a period of preincubation between preparation of platelet-rich plasma and ad...

The effects of intravenous infusions of glyceryl trinitrate and nifedipine on systemic haemodynamic function, coronary haemodynamic function, and global myocardial metabolism were compared in two groups of eleven patients with unimpaired left ventricular function undergoing elective coronary artery operation who were anaesthetised with high dose fentanyl. Severe post-sternotomy hypertension dev...

OBJECTIVES To evaluate the use of topical glyceryl trinitrate (GTN) ointment as an adjunct to periprostatic nerve block in reducing pain associated with transrectal ultrasonography (TRUS)-guided prostatic biopsy. PATIENTS AND METHODS In all, 148 consecutive patients (mean age 67.0 years) having their first TRUS-guided biopsy were randomized to receive either 0.2% GTN ointment or placebo 10 mi...

BACKGROUND Ambient air pollution has been associated with increased cardiovascular morbidity and mortality. In Reykjavik, Iceland, air pollutant concentrations exceed official health limits several times every year. The aim was to study the association of concentrations of NO2, O3, PM10, and H2S in the Reykjavik capital area with the dispensing of anti-angina pectoris medication, glyceryl trini...

Introduction:Serratia marcescens is a gram-negative pathogen of many species. Its pathogenicity and survival are linked to its capacity build biofilms as well strong inherent resistance antimicrobials cleaning agents. Objectives: To analyse the impact glyceryl trinitrate (GTN) on gene expression QS-related genes (rssB, rsmA,and pigP) S. marcescens. Methodology: The broth microdilution technique...
